Answer:
number 10
dy/dx =(dy/dt).(dt/dx)
now find
dy/dt=4t-1. , dt/dx=1
so : dy/dx=(4t-1).(1)
dy/dx= 4t-1 ,we have x=t-3-----> t=x+3
subtitute at t
dy/dx= 4(x+3)-1=4x+12-1= 4x+11
Answer:
its c i tink but im not completly sure
Step-by-step explanation:
2f +4f +2 -3
combine the like terms to get 6f-1
so yes they are equivalent
2f+4f+2-3 at f=3 would also be 17
Answer:
the answer is 17.60
Step-by-step explanation:
if im not mistaken the answer is 17.60. this is because 1/3 of 24 is 8, and 12x2 (the two kids) equals 24, and 60% off of 24 is 9.6. 8+9.6 is 17.6(0) :)
First, we know that y is equal to -8x, so we can move the -8x to replace y in the first equation, then in the first equation we get -8x=6x-14, subtract 6x on both sides, -14x=-14, x=1
